plot_hazard

<code>plot_hazard</code> plots the shape of estimated hazard function in respect 
to duration, given a set of values for the duration and risk equations 
covariates. Confidence intervals are provided through simulation.

An implementation of split-population duration regression models.
Unlike regular duration models, split-population duration models are
mixture models that accommodate the presence of a sub-population that is
not at risk for failure, e.g. cancer patients who have been cured by
treatment. This package implements Weibull and Loglogistic forms for the
duration component, and focuses on data with time-varying covariates.
These models were originally formulated in Boag (1949) and Berkson and Gage
(1952), and extended in Schmidt and Witte (1989).
